E60 / E61 (2004 - 2010) BMW 5-Series E60 Sedan was first seen in the Unites States in the fall of 2003 with a 2004 Model Year designation. The E61 wagon followed shortly there after. The E60/E61 5 series is now available as a 528i, 528xi, 535i, 535xi, 550i and a 535xi sports wagon! -- View the E60 Wiki

new member here and looking for info on a tune or chip for the 2007-2008 535i. is it a flash of the PCM or a inline chip that modifies the boost? with the chip is it faster than a 550? what about a CPO vehicle with a extended warranty from dealer will it void that warranty? can it be removed or backed out without leaving a signiture?

They are expensive because they are the only tunes sanctioned by BMW so there's a price to pay. JB4 is a Great Choice if you want to remove the tune prior to getting your car worked on every time so you don't void the BMW warranty.

Forget cobb. get a dinan tune. No issues with the warranty because BMW works with the directly with the company.

Forget get Dinan , No issuses with my Jb4 and Cobb installed plus the fmic dp's intake and exhaust , and a 3qt bottle of meth under the hood. Because I work with my SA's and techs, and ask only for a phone call before they plug my car into the mothership.

You guys are so scared, talk nice ask open end questions "lets say I did put bigger turbos on my car?" Get a feel for them coffee and donuts gose a long way with these guys. You want them to be your friends.

My cars been to 2 different dealerships this way never a problem. And I broke plenty.

Dinan are, by far, the weakest tune and yes, while they do warranty their work they are extremely overpriced for the money. There are thousands of N54 engines running around with JB4 and Cobb's without problems. Any tune you get will tax your components more (plugs, injectors & coils primarily) but with a Dinan you pay twice as much for half the fun of a cobb or JB4. I don;t like monkeying around under the hood so I went with a cobb. If I need to take the car in I plug it in, remove the run (10 minutes) and, voila, i;m done. Of course, I've also got downpipes, an FMIC, intake, Meth, Exhaust, a charge pipe and aftermarket DV's so, obviously, there is alot more going on but as was said above, talk with your SA and gauge how open they are.

The Cobb AccesPORT is one of the best tunes that are available for the N54. It gives the user full control and you'll be able to run different maps depending on the mods you have on your car. The Cobb saves your stock map file during the install and it'll flash your car back to it's original settings during the uninstall process. It'll wipe the ECU of any trace and you wont have any issues!

As i had told in another post dinan is for someone who cares about warranty, that being said if you have a new car.. you will be covered under your 4yr factory warranty. If you are in an extended warranty or CPO, you will know when you face an issue how the stealership responds.. Dinan can come to rescue you for the first 2 yrs thats it..

In terms of performance, Dinan is the weakest which is being explained in detail in many posts. You can do a search.

I just cannot imagine of spending around 2K for such a lousy tuning...

Xclone has a Cobb stage 2 with lots of mod added to it, Its an "M5" in terms of performance and power. And i always like to get something that i enjoi the most, so for me cars like xclone is a dream come true..

If 2008 I was getting a new cat, wanted the protection of the Matching warranty and was not a DIY guy

Dinan is big $$ for little gain. Even a JB+ piggyback has same power and costs 1/10th.
That said any tune will obviously improve performance. It's just a matter of bang for buck.
Some people might sleep better at night with the Dinan, that's fine. But there are better choices in terms of performance, and they all cost a lot less. Cobb you just remove it from the ODB port, JB4 you turn off on the steering wheel.
Show me one instance where someone had their waranty voided due to an aftermarket tune. I have yet to see a single post on that.

I installed S1 Agressive in June and havent looked back..been a pretty impessive car to drive. Now, I am taking my car tomorrow for battery change, so I uninsalled and flashed original curves. That alone (ease of installing/uninstalling) makes it worth every penny. But what blew me away was the difference I noticed now that the S1 Aggressive curve has been uninstalled. This car is a dog, now this is relative of course. Its just interesting that I noticed the amazing impact of COBB after uninstalling..I cant wait for new battery so I can go back to COBB.
Go COBB and dont look back
